4-1437290-0 / 2-6447232-3 TE SUPERSEAL 34-Pin ECU Connector — Wire-to-Board
The 4-1437290-0 and 2-6447232-3 are TE Connectivity SUPERSEAL series 34-pin ECU connectors for wire-to-board (PCB socket) applications. The SUPERSEAL series is TE Connectivity’s premium sealed automotive connector platform, providing IP67 moisture protection for ECU and control module connectors in demanding underhood environments. The 34-pin configuration is used in high-complexity ECU applications requiring a large number of signal, power, and ground circuits in a single sealed connector interface.

TE SUPERSEAL Series — ECU Connector Standard
- IP67 sealed — SUPERSEAL connectors provide dust-tight and temporary immersion protection; the standard for ECU connectors in underhood locations
- Wire-to-board interface — the PCB socket (2-6447232-3) mounts directly to the ECU PCB; the wire-side connector (4-1437290-0) connects the wiring harness to the ECU
- 34-pin high-density — accommodates complex ECU wiring requirements including multiple sensor inputs, actuator outputs, CAN/LIN bus, power, and ground circuits
- TE Connectivity OEM standard — SUPERSEAL is used by major OEMs including VW, BMW, Ford, GM, and many others for ECU and control module connectors
Typical Applications
- ECU wire-to-board connector repair and replacement
- Engine management system connector replacement
- Transmission Control Unit (TCU) PCB connector repair
- ABS/ESP module connector replacement
- Custom ECU wiring harness fabrication
Frequently Asked Questions
Q: What is the difference between the wire-side and PCB-side connectors?
The 4-1437290-0 is the wire-side connector — it connects to the wiring harness and mates with the PCB socket. The 2-6447232-3 is the PCB socket — it is soldered directly to the ECU circuit board. For wiring harness repair, you typically only need the wire-side connector (4-1437290-0). The PCB socket replacement requires ECU board-level repair.
Q: Do I need special tools to assemble SUPERSEAL connectors?
Yes — SUPERSEAL connectors use individual wire seals that must be installed before crimping. Use a TE Connectivity-compatible crimping tool for SUPERSEAL terminals. After crimping, insert the terminal with wire seal into the housing until the locking tab clicks. A terminal insertion tool is recommended for 34-pin connectors to avoid bending adjacent terminals during assembly.
